Definitions

  • the present invention relates to a cut resistant glove, and a method for manufacturing a cut resistant glove.
  • cut resistant gloves for use in operations in which a sharp edged tool is used, operations in which glass, metal plate, etc., with a sharp edge is used, and the like, cut resistant gloves knitted using a ground yarn having a string made of a metal or glass fiber as a core material have been known.
  • the string and a support yarn made of an organic fiber provided along the string are used as a core material, and a cover yarn is wound around the core material (see Japanese Patent Nos. 4897684 and 5349797 ).
  • sticking out of the string due to cutting is prevented by way of the support yarn, whereas deterioration of the texture is prevented by the cover yarn.
  • an additional yarn having a favorable texture is used to carry out plating knitting such that the additional yarn is arranged to be situated on the inner surface of the glove, thereby improving the texture and/or fit.
  • the following cut resistant gloves have been proposed: a cut resistant glove knitted from two different yarns, one of which contains cut resistant fibers and the other of which contains fibers having a hardness that tends to dull a cutting blade (United States Patent No. 6161400 ); a cut resistant knitted glove made by double-sided knitting using several yarns in order to form an outer side and an inner side (European Patent Application, Publication No. 2468122 ).
  • the ground yarn has a great thickness.
  • a ground yarn and an additional yarn are used to knit a glove of at least 13 gauges, due to a limitation of the thickness of the yarn which can be used in a high-gauge knitting machine, as generally referred to, of at least 13 gauges; therefore, it is inevitable to make the setting of the thickness of the additional yarn smaller, as compared with the thickness of the ground yarn.
  • the effect of the additional yarn by the plating knitting becomes inferior, and for example, the ground yarn is likely to be exposed from the gap of the additional yarns, whereby it may be difficult to ensure the texture and/or the fit of the glove.
  • the conventional ground yarn becomes less flexible, thereby being more likely to give hard feel on touch. Accordingly, even in the case of gloves composed of smaller stitches of at least 13 gauges for which higher flexibility is expected, as compared with gloves composed of larger stitches of less than 13 gauges (for example, 10 gauges), the flexibility may be insufficient when the conventional ground yarn is used.
  • the present invention was made in view of these circumstances, and an object of the invention is to provide a cut resistant glove having stretchability and being superior in the texture and fit while a string made of a metal or glass fiber is prevented from sticking out, irrespective of the gauge number.
  • a cut resistant glove having a glove main body is manufactured by plating knitting using a ground yarn and an additional yarn, in which the ground yarn includes a core material, and a cover yarn wound around the core material, the core material having a string made of a metal or glass fiber, the core material further having a support yarn made of an organic fiber arranged along the string, an average thickness of the support yarn being no less than 45 dtex and no greater than 100 dtex, and the additional yarn being made of an organic fiber, and in which the ratio of the average thickness of the additional yarn to the average thickness of the ground yarn is no less than 0.9 and no greater than 2.5, and the cut resistant glove is composed of stitches of at least 13 gauges.
  • an average thickness of the ground yarn is no less than 135 dtex and no greater than 440 dtex
  • an average thickness of the additional yarn is no less than 135 dtex and no greater than 670 dtex
  • an elongation rate of 30-g load to 3-g load of the additional yarn is no greater than 30%.
  • the additional yarn in the cut resistant glove prevents the ground yarn from being brought into contact with the hand through exposure out from the stitches.
  • the texture and/or the fit of the glove can be readily secured by providing a thinner cover yarn of the ground yarn, even when the cut resistant glove composed of smaller stitches of at least 13 gauges is to be knitted.
  • influences from the ground yarn on the glove can be reduced, whereby necessary flexibility for the cut resistant glove composed of smaller stitches of at least 13 gauges is likely to be secured.
  • the cut resistant glove is superior in texture even when the cut resistant glove is composed of stitches of at least 13 gauges.
  • the core material thus further has the support yarn made of an organic fiber arranged along the string and the average thickness of the support yarn falls within the above range, an effect of preventing the string from cutting is enhanced.
  • the support yarn and the additional yarn can prevent the ground yarn from being brought into contact with the hand through exposure out from the stitches.
  • the texture and/or the fit of the glove can be readily secured by providing a thinner support yarn and/or cover yarn of the ground yarn.
  • the average thickness of the cover yarn of the ground yarn is preferably no less than 45 dtex and no greater than 100 dtex. When the average thickness of the cover yarn of the ground yarn thus falls within the above range, the sticking out of the string can be prevented, and the texture of the glove is more improved.
  • the elongation rate of 30-g load to 3-g load of the additional yarn is no greater than 30%.
  • the elongation rate of 30-g load to 3-g load of the additional yarn thus falls within the above range, tightening in the glove is prevented, and the sticking out of the string is prevented.
  • the average thickness of the ground yarn is no less than 135 dtex and no greater than 440 dtex, and the average thickness of the additional yarn is no less than 135 dtex and no greater than 670 dtex.
  • the average thickness of the ground yarn thus falls within the above range, more superior cut resistance is exhibited, and the cut resistant glove composed of stitches of at least 13 gauges is more superior in texture. Additionally, when the average thickness of the additional yarn thus falls within the above range, the cut resistant glove is more superior in the fit of the glove as well as the feel on touch, and exhibits superior workability.
  • the additional yarn preferably includes a core yarn, and a cover yarn wound around the core yarn.
  • the additional yarn is thus composed of a core yarn, and a cover yarn wound around the core yarn, the texture of the glove is further improved while necessary stretchability of the additional yarn is secured.

  • an elongation rate of 30-g load to 3-g load of the additional yarn is no greater than 30%.

Next, a weight of 3 g and a weight of 30 g are each suspended, and each interval of the bench marks is measured. The elongation rate is determined from the bench mark intervals attained when each weight was suspended.

Accordingly, by adjusting the elongation rate of 30-g load to 1-g load and/or the elongation rate of 30-g load to 3-g load of the additional yarn to be no greater than a certain value, it is proven that excessively strong tightening in the glove can be avoided, and uncomfortable feeling resulting from sticking out of the string, etc., is less likely to occur.
  • Example 1 to 4 when Examples 1 to 4 were compared with Example 8, Examples 1 to 4 having a greater elongation rate of 3-g load to 1-g load of the additional yarn is superior in fit than Example 8 in which the cotton yarn having low stretchability was used for the additional yarn. From this finding, by adjusting the elongation rate of 3-g load to 1-g load of the additional yarn to be no less than a certain value, it is proven that appropriate stretchability is imparted to the glove, and thus the fit is likely to be attained.
  • Example 1 when Example 1 is compared with Example 9, it is revealed that Example 1 in which the ground yarn is arranged on the outer surface side received a better evaluation of the uncomfortable feeling.

  • This cut resistant glove exhibited further improved fit.
  • the draft setting value was 2
  • the cover yarn is fully extended before the returning force of Spandex increases.
  • the draft setting was low
  • the thickness of Spandex is great in particular, the excessive tightening is loosen, whereby the fit tended to be improved.

  • the cut resistant glove exhibited further improved fit.
  • An increase of the number of winding per unit length of the cover yarn permitted the additional yarn to be tightly squeezed, whereby a decrease of the stretchability was enabled. From this result, it is considered that when the additional yarn has excessive stretchability, the stretchability can be controlled by adjusting the number of winding of the cover yarn.
  • Example 10 and Example 11 were obtained. Evaluations similar to those in Example 1 were made on these cut resistant gloves. The results are shown in Table 4.
